摘要:
A locking device for a cover of a magnetic tape cartridge (3) for locking a pivotable cover (4) for covering magnetic tape inlet and outlet ports (16 and 17) of the magnetic tape cartridge, including a projection (70) formed on an arm (67) for pivotally supporting the pivotable cover which is engageable with an engaging claw section (74) of a locking member (73) which further includes an operation section (75) and a resilient section (76). The locking member is pivotally supported on a magnetic tape cartridge case (3) and urged by the biasing force of the resilient section to bring the engaging claw section into engagement with the projection. The operation section of the locking member is located in a position in which it is capable of cooperating with an unlocking pin moved from three directions, to thereby give latitude to the process for loading a magnetic tape cartridge on a magnetic recording and reproducing apparatus.

The tape cartridge comprises a case (1), a lid member (10) having a front plate (11) and rotatably mounted on the cartridge case so be rotated between a closed position and an opened position, an opening (31) defined in the bottom portion of the front plate of the lid member for receiving a standard pin of a recording device and butting means (32, 33) projecting from the front end of the bottom wall of the cartridge case to protrude in the opening of the lid member up to a position substantially corresponding to the middle of thickness of the front plate when the lid member is in the closed position.
摘要:
A tape cartridge is arranged so that when an upper lid of a pocket portion of the tape cartridge is in a position for opening the upper side of the pocket portion, the upper lid is positioned above an upper surface of a casing body so that a lower surface of the upper lid faces the upper surface of the casing body through a gap in which a member of a recording/reproduction apparatus for depressing the cartridge can be placed. When the upper lid is in the position for opening the upper side of the pocket, the cartridge depressing member of the recording/reproduction apparatus is placed in the gap to depress the cartridge, whereby the cartridge can be stably depressed to and mounted in a predetermined position in the recording/reproduction apparatus when the cartridge is loaded in the apparatus.

A tape loading mechanism for a magnetic recording and reproducing device to pull out a magnetic tape (14) from a tape cassette (11) containing the magnetic tape to wind the magnetic tape for a predetermined winding angle around a rotating cylinder (18) having a rotating head mounted thereon comprises incoming-side tape pull-out guide device (15, 17, 41, 47) for pulling out the magnetic tape (14) from the tape cassette (11) to form an incoming-side portion of a tape running path located between a tape incoming side of the rotating cylinder (18) and the tape cassette (11) upon loading the tape (14), the incoming-side tape pull-out device (15, 17, 41, 47) having a plurality of tape guides (15, 17) which are inserted into an opening of the tape cassette (11) to be engaged with a base side of the magnetic tape (14); first outgoing-side tape pull-out guide device (19, 21, 22, 23, 27, 57, 58, 59) for pulling out the magnetic tape (14) from the tape cassette (11) and winding the tape (14) for a predetermined angle around the rotating cylinder (18) downwardly in a spiral form upon loading the tape (14), the first outgoing-side tape pull-out guide device having a first inclined tape guide (23) to change the running direction of the magnetic tape (14) upwardly; and second outgoing-side tape pull-out guide device (1, 24, 25, 26, 52) for forming an outgoing-side portion of the tape running path between the tape outgoing side of the rotating cylinder (18) and the tape cassette (11) in cooperation with the first outgoing-side tape pull-out guide device, the second outgoing-side tape pull-out guide device having a second inclined tape guide (25) always located outside the tape cassette (11) to engage with a magnetic surface side of the magnetic tape (14) running from the first inclined tape guide (23) to return the running direction of the tape (14) to the height of the tape cassette (11).
摘要:
Tape tension controller comprising: a reel-base (3) on which a cassette having a supply reel and a magnetic tape (4) wound around said supply reel is accomodated; a head cylinder (32) having a cylindrical wall onto which said magnetic tape fed from said cassette is wound; a movable detecting arm (5) engageable at one end thereof with one surface of said magnetic tape between said cassette and said head cylinder for detecting the tension in said magnetic tape, the movement of said detecting arm being responsive to the change of said tension; breaking means (10) controllable by said movement of said detecting arm for resisting the rotation of said supply reel with a breaking force so as to maintain a substantially constant tension in said magnetic tape; and urging means (14, 16) provided in the vicinity of said one end of said detecting arm for enlarging a contact surface of said one end of said detecting arm and said one surface of said magnetic tape.

摘要:
The magnetic recording/reproducing apparatus for recording onto or reproducing from a magnetic tape housed in a cassette by using a rotary magnetic head has tape drawing-out means (6, 8, 9, 55) for winding a portion of the tape (53) between the two reels in the cassette around the rotary magnetic head (2) by a predetermined angle. The magnetic recording/reproducing apparatus has further tape driving means (3, 57) for feeding the magnetic tape at a constant speed, reel driving means (24) for driving either one of the two reels so as to take up the magnetic tape in the reel driven by the reel driving means, and braking means (18,19, 20) for braking the rotation of the reels. Each of the above described means is selectively actuated by a ring-shaped cam operating member (64) provided in the outer peripheral surface or the inner peripheral surface thereof with cam surfaces each for effecting the operation of the respective means in response to the mode of operation of the magnetic recording/reproducing apparatus. The selective operation is specifically determined by the rotational position of the ring-shaped cam operating member, and the rotational position is varied in response to the mode of operation. Detecting means (62, 72) for detecting the rotational positions is provided in the ring-shaped cam operating member.
